Fix pyright type hinting issue with the project_dribs iterable in the test

[loleg]

• Added list[dict] type hint to project_dribs to resolve the pyright type inference issue.
• Removed the # TODO comment and the # pyright: ignore comment as the type issue is now resolved.
• Added pyright to the dev dependency group in pyproject.toml so it can be used for local static type checking.
